The sucrose move in source to sieve by active transport.
<h3>What is active transport?</h3>
Active transport is a type of transport in which the cell expends energy to move solutes against their concentration gradients. The sodium-potassium pump is an example of active transport. Active transport differs from passive transport in that the cell does not expend energy.
In this case, the sucrose moves from companion cells into source to sieve elements by active transport. This reduces the water potential of the source to sieve element by osmosis, which increases the hydrostatic pressure.

Reasoning
Q6: Based on all the other questions talking about common ancestors I deduced that to find a “common” ancestor they need to find things that are the same.
Q7: All arthropod have a exo skeleton for example a lobster or crab. They all have a head, abdomen and thorax for example ants. They all have legs with joints for example a spider.
Q7:So bones are traveled down by ancestors so the types of bones stay the same but natural selection has changed them to better fit their environment.
Dopamine is predominantly engaged in gross, unconsciously occurring motions of the skeletal muscles, which has an impact on motor function.
Dopamine is a neurotransmitter that predominantly influences motor control and is involved in large-scale, unintentional skeletal muscle contractions. Dopamine also contributes to emotional reactions. Parkinson's disease is characterized by a dopamine deficit and tremors or uncontrollable quivering motions in the sufferer. Acetylcholine contributes to the speedy transmission of nerve impulses by spilling into the synapse region. Norepinephrine affects arousal maintenance, dreaming, and mood modulation. Serotonin causes sleep, changes sensory perception, regulates temperatures, and plays a role in the regulation of mood.
